Returns the default material scheme used by the render system.
Systems that use the RTSS to emulate a fixed function pipeline (e.g. OpenGL ES 2, GL3+, DX11) need to override this function to return the default material scheme of the RTSS ShaderGenerator.
This is currently only used to set the default material scheme for viewports. It is a necessary step on these render systems for render textures to be rendered into properly.

This function was created because of Metal.
The Metal API doesn't have a 'device->clear( texture )' function. Instead we must specify we want to start rendering to a cleared surface. This allows mobile TBDR GPUs to begin rendering without having to load any data from memory (saves a lot of bandwidth and battery).
Ogre will first issue a clear, then begin executing the shadow node (which switches to the shadow map) then switch back to the original rtt to resume regular rendinering. In this common case we want to delay the clear, but _setRenderTarget is clearly not an trusted indication (we would get many false positives).
previousRenderTarget | RenderTarget that was being used (and we should clear if we have to). |
Reimplemented in Ogre::MetalRenderSystem.

In Direct3D11, UAV & RenderTargets share the same slots.
Because of this, we enforce the same behavior on all RenderSystems. An unfortunate consequence is that if you attach an MRT consisting of 3 RTs; the UAV needs to set at slot 3; not slot 0. This setting lets you tell Ogre the starting slot; so queueBindUAV( 0, ... ) can goes to slot 3 if you call setUavStartingSlot( 3 )
